What is your budget, and from where can you buy it? Can you order from Newegg.com?

Any quality 550W power supply is enough. AMD recommends a 600W peak-rated PSU to power a system that has two 6870s in it, but any quality 550W power supply that I recommend is a continuous-rated unit which means it has much more power than any 600W peak-rated unit.

The TX650 is more than enough.

Meh, not really. The TX650 is overkill because even a quality 550W power supply is enough (for example, the 550W Antec TruePower New).

A quality 1200W power supply would be required for a system with like 4 high-end video cards.

Video cards and CPUs consume most of the power while everything else is almost on the sidelines. So the main considerations are almost always the video card, and then the CPU. Although, another consideration for some video cards and CPUs is how much they will be overclocked. For example, I remember being told that the HD 6900 series draws much more power when overclocked.
